This is a well conceived, carefully written book. The description of identical twin sisters, Catriona and Ellice, varies from reality to the amazing other world they created for themselves as children to escape from the realities of their upbringing. In the mix is the boy, Ross, who figures large in the story. Cat as she is known leaves El to hide in California from all that is troubling her. She returns when her sister disappears and that is the theme of a gripping, compulsive read. Bit by bit, the truth emerges to take the reader to a rewarding climax. This is not just a story of a damaging childhood and later pursuit of a missing person. The context that has been created is psychologically impressive and testing of the imagination. Set in Edinburgh mainly, the author uses that setting to advantage. I recommend this book strongly. It is a very significant achievement and contribution to fiction.

Great thriller, with so many plot twists, right up until the end. Kept me guessing, then changing my mind. Had to read in one sitting because I couldn't put it down. A real page turner, that reminded me a little of the film 'sleeping with the enemy', and the great novel 'flowers in the attic', coming together. Well written and definitely worth a read.

It seems unfair to the author to say I was surprised by how much I enjoyed reading this but it’s the truth. Cat returns to her childhood home after her twin sister El goes missing and has to sort which memories are fact and which are fiction. At first I thought Mirrorland was a bit gimmicky but I really got drawn into the story as a whole and from the half way point I was totally engrossed. There was much here that surprised and at times shocked me and I never felt like I had it all worked out. I hope this is a great success and I can’t wait to see what the author Carole Johnstone does next. Highly recommended.

Cat and El grew up in a stately stone manor in Edinburgh. The house was full of hidden corners and nooks, strange shadows and crumbling decay. The sisters played a make believe world there, one they called Mirrorland, a place where they could hide from the things that frightened them. Years later, Cat is forced to return when El disappears. She must go back to Mirrorland to follow the treasure map that El left for her to uncover the secrets of their past. Atmospheric and Gothic in nature, this book’s central and most important character is Mirrorland itself

Thank you NetGalley and HarperCollins UK for granting me an e-galley of Mirrorland to review!

Cat and El are identical twins supposedly able to sense even the slightest pain in one another. Throughout their childhood, they spent their lives inside a fantasy world Mirrorland - a world populated by pirates, outlaws, clowns, and prisoners. One fateful day, something happens and they had to leave behind Mirrorland forever. After being estranged for twelve years, however, El has disappeared and Cat finds herself returning to Mirrorland where El returned with her husband Ross (a mutual friend Cat knows all too well). While El is presumed dead, Cat is suddenly thrown into Mirrorland once again for a treasure hunt bearing the prize of her sister's fate.

Every chapter in Mirrorland brings about a new surprise, each revelation making me question what is real and what is not. The fantasy that is Mirrorland is deeply rooted in Cat and El's childhood, blurring the line between reality and fantasy. Mirrorland's present timeline forces Cat to increasingly drag out memories in Mirrorland and reconcile them with the horrific reality of what happened the day they left Mirrorland. Many painful and uncomfortable truths are brought to the open as Cat and El's relationship is also dissected, bringing light to how the events in Mirrorland have affected them.

The writing in Mirrorland is scarily atmospheric to the point I felt I had to take some breaks to reorient my sense of reality, but at the same time the book is incredibly gripping. Many of the stories, the adventures had in Mirrorland are imbued with darker truths touching on horrible abuse, love, betrayal, and familial bonds (e.g. motherly and sisterly love). Not one aspect of Mirrorland is wasted: it is chock-full of subtly planted arsenals to change the narrative; and just when I thought I had the truth all figured out, another information I'd dismissed as a throwaway line for "worldbuilding" in Mirrorland returns to add yet another massive piece of the puzzle I've no idea how large. The chills and misdirections are well-planned, although some of the revelations in the book may prove uncomfortable.

Carole Johnstone's Mirrorland is a perfect blend of fantasy, mystery, and thriller as Johnstone takes the presumed innocence of childhood fantasy and rips it apart - showing the dangers of letting others shape your imagination. Mirrorland had been Cat and El's safe haven, and the degree to which (and how) it went horribly wrong is the true tragedy of the book. Ultimately, Mirrorland is a story of loss, healing, and recovery from tragedy, years of abuse, and manipulation.
